I too have Gout and don’t drink. Losing weight kicks it off the worst or sudden exercise. Red meat, orange juice and mushrooms are the very worst for me. Dehydration can be a factor too. Bloody horrible. Be kind to your feet, don’t bang them or knock them. I’ve also started wearing larger shoes with inserts and looser socks. I know it sounds like a faff, but I’ve completely turned it around touch wood.
Just started with Huel so I can’t help there, but I’m not particularly concerned about the ingredients. Good luck. It’s just the worst.
